N is the usual vibrating-bar or key-board Heretofore machines of thisclass have been foo 5o hung by side arms 0 onthe shaft D and exprovidedwith a single registering mechantending across the entire series ofkeys. ism, consisting eitherof a ser1es of individualregistering-wheels, one for each key and each registering only theoperations of its key, or else a single registering-wheel common to allof the keys and actuated to different degrees by keys of differentvalues and usually connected to a train of supplemental wheels to whichthe amounts registered by the revolution of the primary Wheel weretransferred. Each of these forms of registering mechanism possessesadvantages over the other. In the former the total amount registered byeach key is preserved and the proprietor at the end of a days businessisenabled to judge of the character of the sales made and can ascertainjust how many sales of each value there were, while in the latter thetotal amounts registered by all the keys are added together and theproprietor is unable to tell anything about the character of the salesmade during the day. In the former mechanism the total amounts indicatedon the respective wheels have tobe added together in order to get theaggregate amount of the sales of the day, while in the latter they areall added together on the registering mechanism of the machine and thetotal can be read off at a glance. In my present machine I have theadvantages of both these forms of mechanism; and to that end one featureof my invention consists in combining with a single set ofoperating-keys and their indicating-tablets two sets of registeringmechanisms, both actuated by the same keys, the one consisting of aseries of individual registering-wheels which preserve a separateregistry of the total amount registered by each key, and the other aself-adding mechanism which adds into one common total the amountsregistered by all the keys, so that when any key of the series isoperated its corresponding indicator is exposed to view and its value isregistered on its individual registering-wheel and also added in thecommon total on the self-adding mechanism. The first of these sets ofregistering mechanisms is illustrated in Fig. 1, where E E represent twobanks of individual registering-wheels strung on shafts F F, extendingacross the machine. There are as many wheels in each bank as there areoperatingkeys, each wheel of the lower bank being turned one number byeach operation of its corresponding key, through the medium of thepivoted weighted dogs G, carried by the operating-keys and engaging theratchets of the wheels. The wheels of the lower bank bearon theirperipheries a series of numbers in multiples of the values of theircorresponding keys, while those of the upperbank bearon theirperipheries a series of numbers in multiples of the total amountsregistered by complete revolu'tions of their corresponding wheels in thelower bank. The ratchet on each wheel of the lower bank has one toothlarger than the rest to engage the ratchet of its corresponding wheel inthe upper bank and turn it one notch at each complete revolution of thewheel of the lower bank. Suitable readingopenings ll ll" in thecovering-plate 1 extend across each bank of the wheels and enable thetotal registered amounts registered 011 the wheels to be read off andadded up.

The above constitutes the individual registering mechanism, whichpreserves separately a record of the sales of each value, so that at theend of the days business the proprietor is enabled to tell from thewheels E E of the five-cent key just how many live-cent sales have beenmade, from those of the tencent key just how many ten-cent sales havebeen made, and so 011 through the entire series.

The self-adding registering mechanism, in which the registrations of allthe keys are added into one common total, is shown more particularly inFig. 2, where J, K, L, M, and N are a set of registering-wheels carriedon a supporting-plate O, and adding one onto the other and indicating,respectively, cents, dollars, and tens, hundreds, and thousands ofdollars. The wheels K L M N are an ordinary set of Geneva-stop wheelsbearing on their faces multiples of one from O to 9, inclusive, thewheel L being turned one number at and by each complete revolution ofthe wheel K, the wheel M being actuated in a similar manner by the wheelL, and the wheel N by the wheel M. The dollar-wheel K is turned onenumber at each complete revolution of the cent-wheel, which latter bearson its face a series of numbers in multiples of five from 0 to 95, andis also actuated directly by the operation of the keys of the dollar setat the left-hand side of the machine, all in the manner and by the meanshereinafter described. Secured to the shaft of the wheel J is a pinionP, having twenty teeth and meshing constantly with a larger gear-wheelQ, carried on a spindle or stud R, screwed into the plate 0 and havingin this instance eighty teeth. Secured upon the face of the wheel Q is aratchet-wheel S, also having eighty teeth. Loosely hung on thesupporting-stud of the wheel Q is an arm T, carrying at its outer end apawl U, normally pressed into engagement with the teeth of the ratchet Sby a spring secured to the outer end of the arm T. This arm T isconnected by a pivoted link Vto an arm \V, pivoted to an inclined bar X,extending across the right hand or cent set of keys and hung by sidearms Y Y on the pivotal shaft D of the operating-keys C. The innersupporting-arm Y of the bar X has a downward bend forward of its centralportion, as shown in Fig. 1, to enable it to clear the vibrating bar orkey-board N, which extends entirely acrossend of of the bar X in normalposition rests directly on the ninety-five-cent key, so that thebar isgiven its full movement by the operation of that key, while its loweredge is normally at such distance above the live-cent key that theoperation of the latter moves the bar only one-nineteenth, as far as theninetyfive-cent key. The adjustmentof the parts is such that the liftingof the bar X by the operation of any key moves the wheel Q, through themedium of the arm W, link V, arm T, pawl U, and ratchet S, just as manyteeth as there are fives in the value of the operated key, therebyturning the pinion P on the shaft of the wheel J acorrespondingnumber ofteeth and registering the value of the key on said wheel, all as will bereadily understood.

Z is a holding-dog pivoted to the plate 0 and engaging the ratchet S toprevent said ratchet and the wheel Q moving backward as the pawl U slipsup over the teeth of the ratchet upon the lifting of the bar X by theoperation of a key. The ratchet and wheel are turned to effect theregistration upon the return stroke of the key and resetting of the barX. The shaft of the wheel K also has secured to it a pinion P havingtwenty teeth and constantly meshing with a gearwheel Q, carried on astud R, screwed into the plate 0, and having secured upon its face aratchet S. The wheel Q has eighty teeth, the same as the wheel Q but theratchet S has only forty teeth, so that the turning of the ratchet onetooth will turn the wheel Q and the pinion P two teeth each; but as thelatterhas twenty teeth,while the wheel key K, to whose shaft it issecured, has only ten numbers, the turning of the wheel Q and pinion Ptwo teeth will turn thewheel Konly one number. and thus the latter isturned one number for each tooth of the ratchet S. Loosely hung on thestud R, which carries the wheel Q, is a lever A, one of whose armscarries a pawl B, spring-pressed into engagement with the ratchet S. Theend of this arm of the lever is normally pressed by a spring 0, engagingits opposite end against a snail-cam D, secured to the shaft of thewheel J, as shown in dotted lines in Fig. 2. As the wheel J is revolvedthe cam D gradually depresses the end of the lever A and moves the pawlB backward over one tooth of the ratchet S until just as the wheel Jcompletes a revolution and its 0 is brought to its reading-opening theend of the lever A slips off the cam and is thrown upward by the spring0, pressing its opposite end downward, causing the pawl B to turn theratchet S forward one tooth, thereby turning the wheel S and pinion Ptwo teeth and the wheel K one number, and thereby adding one dollar tothe amount registered on the latter. In this manner at each completerevolution of the wheel J the wheel K is turned one number, and thedollar registered by one complete revolution of the wheelJ is the wheelJ begins at zero again.

added onto the wheel K and the registry on The wheel K is also actuateddirectly by the keys of the dollar set, in the same manner that thewheel J isactuated by the wheels of the cent set, through the medium ofan arm T ,loosely hung on its supporting-stud and carrying a pawl U,engaging the ratchet S, a link V connecting said arm to an arm pivotedto an inclined bar X, extending across the keys of the dollar set andhung by side arms Y Y on the shaft 1). There are reading-openings K inthe rear vertical portion of the covering-plate I, just in front of thewheels J, K, L, M, and N, through which the uppermost numbers on thelatter can be seen.

Pivoted between the keys 0, just in rear of the bars X X, Fig. 1, are aseries of hooks G, whose rear sides rest against lugs 1, proj ectingfrom the sides of the keys. These lugs normally rest on rearwardprojections J of the hooks Gand hold the latter thrown backward; but theadjustment and shape of the parts are such that when any key is operatedits lugs I strike the curved rear side of its hook G and throws theupper end of the hook forward over the path of travel of the bar X or X,as seen by the dotted lines in Fig. 1, so that the upper side of the barstrikes the hook and is arrested by it. \Vhen the hooks are thrownforward, the surface of the rear sides from a point just above thenormal position of the lugs I to their upper ends is the arc of a circlestruck from the center of the shaft 1), on which the keys are pivoted,so that after the rear end of a key starts to rise and throws its hookforward into the position shown by the dotted lines its lug moves upit-srear side and holds it in such position until the key is reset. By theemployment of these hooks I prevent any over registration from themomentum of the bars X X in their upward travel. The hooks are all ofthe same length, since the upper sides of the bars X X are inclined aswell as theirlower, so that the space between the upper sides of thebars and points of the hooks varies in width just as does the spacebetween the lower sides of the bars and the tops of the keys. To avoidconfusion in the drawings, the hooks have not been shown in Fig. 2.

My invention is not limited to the employment of the inclined bars X Xfor actuating the registering-wheels J K to different degrees, for anywell-known or suitable means may be employed for that purpose; nor is itlimited to the particular form of the self-adding registering mechanism,as other convenient styles may be substituted for that illustrated inthe drawings.

Any suitable stops (not shown) may be employed for the purpose ofpreventing the operation of two or more keys at once.

Having thus fully described my invention, I claim 1. In a cash registerand indicator, the combination of a series of operating-keys providedwith finger-buttons representing different values, a series ofindicators representing corresponding values actuated thereby, anactuating-pawl for each key, a series of registering-wheels, one foreach key and actuated by its pawl to preserve a separate registry of theoperations of each key, and a registeringwheel common to all of the keysof the same series and actuated thereby to different degrees bydifferent keys to afford a total registry of the values of all of theoperated keys, whereby upon operating any key of the series it actuatesits individual registeringwheel to register its value thereon, and alsoactuates the common registering-wheel to the proper degree to add itsvalue upon the total registry, substantially as described.
